摘要：Gas stripping is an effective means to remove dissolved gases from liquids. To address the drawbacks of previous technologies, a unique planar bubbly cyclone (PBC) for continuous gas–liquid mass transfer is designed. This PBC meets the requirements of gas stripping, including a lower gas-to-liquid volumetric flow rate. A swirling flow and liquid backflow are formed under the constraints of the guide vanes and the cylinder wall. The population balance model accurately predicts the bubble diameter (1 to 6 mm), while the Kawase correlation gives excellent results and is in good agreement with the experimental data (±0.001 m/s). The accurate estimation, based on the assumption of gas plug flow and a well-mixed liquid flow, gives volumetric mass transfer coefficients of 0.15–0.95 s?1 when the gas–liquid ratio was 0.01–1. Overall, the PBC provides an alternative approach to gas stripping, exhibiting a low gas–liquid ratio, long-term capabilities, and good reliability. ? 2025 American Institute of Chemical Engineers.
